Are you using glassfish v2 or v3? In v3, you have a much better way of
doing it by using OSGi facilities to install URL handlers dynamically.
On v2, you have to do it using java.protocol.handler.pkgs system
property. You can edit it in jvm settings screen in admin console. Is it
possible that your hander class is not loadable?

The app, standalone, works fine by modifying the system property java.protocol.handler.pkgs. However, once that code is embedded in a servlet, I get MalformedURLException every time I try to create a URL with the custom protocols. Specifying the property in the admin console doesn't have any effect, although it isn't clear where I would need to do that.

A few hours of searching the documentation hasn't turned up an obvious fix. I don't really care about which servlet container I use, but Glassfish came with Netbeans so I was hoping it would be easy to use.
